Question: A coil of 15 turns and radius 10.0 cm surrounds a long solenoid of radius 2.20 cm and 1.00 x 103 turns/meter. The current in the solenoid changes as I = 7.00 sin 120 t, where I is in amperes and t is in seconds.
A- Find the induced emf (in volts) in the 15-turn coil as a function of time?
Can someone please explain what the heck is going on?
